To allwhom z'tmay concern: a a Y.

Beit known that I, ALoNzo E. RHOADES, a citizen of the United States, and'a resident of Hopedale, county of WVorcester, State of Massachusetts, have invented an Improvement. in Intermittently-Operated Temple Thread Cutters, of which the followingde- SCllptl011,-Ill1 COHDGCtlOn with the accompanyingdrawing, is a specification, like characters on the drawing representing like parts. This invention relatesto improvements in intermittently operable temple thread cutters for looms of the automatic filling replenishing type.

' The object of the invention is to provide a novel and simple temple thread cutter construction that shall be operated for a predetermined period after the operation of the fillingreplenishing mechanism and shall then be rendered inoperative until the nextcall for filling replenishment.

a The purpose of temple thread cutters is to sever the filling ends which project from the selvage edge of the web of cloth after replenishment of the filling and in usual constructions'the temple thread cutting means is actuated upon each beat-up of the. lay.

Hencetheoutting mechanism issubject to a large amount of unnecessary wear. 7

Various means have heretofore been provided, for rendering the operation of the cuttingmechanism intermittent so that it will act, only for a short period after filling replenishment. Such mechanisms, however, havea-lwaysbeen so constructed asto continue to operate for a uniform period of time. r f

Oneof the objects of the present invention isjto provide means for adjusting the action of the temple thread. cutter so that the number of cutting movements. of the thread cuttermay be variedas desired in accordance with the :charactenof the work andconditionsof-operation of thelooml This is accon plished by providing a spring actuated timing. mechanism with means for intermittently rotating the same iii-opposition to its spring and in also providing adjustable means for limiting therotative movement of the timing device when released from the mechanism which rotates it.

A further object of the invention is to provide means for controlling the actuation of the temple thread cutter which can be readily'applied to usual temple stands.

A further object of the invention is to provide novel means for positively actuating the timing mechanism from the movement of the lay, the actuating means preferably being engaged and operated by the hand rai Other objects and features of the invention will more fully appear from the following description and the accompanying drawings and will be particularly pointed out in the claims. 7 i

As the invention is adapted to be applied to loom constructions of the usual type only so much of the loom and loom temple is illustrated in the accompanying drawings as is necessary to illustrate the association of the present invention therewith.

Inthe drawings: I, c

Fig. 1 is a side elevation of a loom temple construction embodying the present invention showing the position of the mechanism and of the controller arm when the thread cutter is held in normal position during the normal operation of the loom and illustrating also in dotted lines the position of the lay and hand rail; Fig. 2 is asimilar view showing the position of the temple thread cutter and of the controller arm after call for transfer;

Fig. 3 is a plan view of the temple stand and temple thread cutter with the present invention appliedthereto together with the controller arm; and,

Fig.4 is an end View on line 4-4 Fig. 3 viewed from the right toward the left, the temple and temple stand being omitted and certain portions of the mechanism shown in section. a

The loom may be of a usual automatic filling replenishing type comprising a lay 1 with its hand rail 2 shown in dotted lines, a breast beam 3, and controller rod 4, the controller rod being provided with an arm 5 adapted 1 to release the. timing mechanism which controls the filling cutting or parting device as will hereinafter bemore fully described. v

The: temple stand 6 maybe of a usual type rigidly secured to a bracket (not shown) mounted upon the'breast beam to the selvage and adjacent to the fell.

shown) in the temple stand acts normally to project the temple rearwardly in the usual manner. The filling parting mechanism is carried by the temple in such a manner that its field of operation lies close This thread cutting mechanism may be of any type. As illustrated herein it comprises a usual stationary blade 10 secured to the temple head and a co-operating flat movable blade 11 slidably and pivotally mounted in ways in the temple head and provided with a hooked end 12 to co-operate with the stationary blade 10.

The movable blade is provided with a downwardly extending heel 13 adapted, when the blade is in operative position, to be engaged by the lay upon its beat-up in advance of the engagement of the lay with the heel 9 of the temple head so that the movable blade will be actuated to cut the filling before the temple head is moved bodily by the lay. A spring 14 at one end coiled about a stud 15 upon the temple arm with its end resting against a shoulder 16 upon the temple arm engages a stud 17 upon the heel 13 of the movable blade and tends normally to retain the cutting blade 11 in operative position;

The construction thus described may be and preferably is that of the usual temple thread cutter in which the cutting blade is actuated upon each beat-up of the lay by engagement of the lay with the heel 13 of the blade before the lay engages the heeel 9 of the temple head.

The. present invention relates to means for withdrawing the cutting blade from operative position and retaining the same in inoperative position during the greater portion of the operation of the loom, with means for permitting the blade to be restored to operative position after call for replenishment and thereafter permitting the actuation of the blade for such number of times as may be necessary to insure proper severance of the filling ends which extend from the selvage of the cloth after transfer.

The mechanism for accomplishing this purpose, which is illustrated herein, comprises a timing device which is mounted upon the temple stand and which is actuated by the movement of the lay and means operated by said timing device for withdrawing the cutting blade from operative position after filling replenishment, with means operable upon actuation of the filling replenishing mechanism to permit the restoration of the cutting blade to operative position.

In the preferred embodiment of the in vention illustrated in the accompanying drawings the timing device is carried by a plate 18 which is adjustably clamped to the temple by machine screws 19 which pass through slots 20 in said plate, washers being interposed between the heads of the bolts 19 and the plate 18. The timing device comprises a rotatable member 21 preferably of cylindrical form mounted upon a stud 22 which projects from the side of the plate 18. The cylindrical member 21 is provided with a series of ratchet teeth 23 extending throughout a segment of its periphery thereof which desirably is somewhat less than half of the periphery of the cylindrical member. A series of cylindrical apertures or pin holes 24 are drilled into the inner face of the cylindrical member selectively to receive a screw or pin 25 which is adapted to engage a lug 26 projecting from the face of the plate 18. A helical spring 27, coiled about the stud 22 and secured at one end to the hub of the rotatable member 21 and at its opposite end to a cap 28 which is pinned to the stud 22, acts normally to force the pin 25, wherever positioned, into engagement with the lug 26 which then arrests the rotative movement of the timing member.

The timing member 21 is also provided with a lug or abutment 29 which is adapted to engage one arm 30 of a lever which is fulcrumed upon a stud 31 projecting from the extension of the plate 18, the other arm 32 of which lever is provided with a headed stud 33 the shank of which is embraced by the hook-shaped end of a link 34 the opposite end of which embraces the stud 17 upon the heel 13 of the cutter. Such connection should be of a character which will permit relative movement between the arm 32 and the heel of the cutter when the cutter, together with the temple head, is moved by the engagement of the lay.

The rotatable timing member is actuated through suitable pawl mechanism operable by the movement of the lay preferably by engagement with the hand rail 2. In the preferred embodiment of the invention illustrated the plate 13 is provided with upwardly extending arms 35 and 36 having guideways for an actuator 37. Desirably the actuator is formed with a section 38 of rectangular cross section having an enlarged head 39 to engage the hand rail, the section 38 being reciprocably mounted in a rectangular guideway in a boss 40 upon the arm 35. Another section 41 of the actuator desirably is of cylindrical form and reciprocably mounted in a suitable guideway in the arm 36. The actuator is normally held in extended position to engage the hand rail by a helical spring 42 which surrounds the cylindrical section of the actuator 37 and abuts atone end against the arm 36 and at its other end against a collar 43 fixedly secured upon said actuator. A collar 44 adjust-ably mounted upon the cylindrical section 41 of the actuator serves by engagement with the arm 36 to limit the movementof the actuator toward thehandrail. A pawl 45, pivotally mounted upon a stud 46, is positioned to engage the teeth 23 of the ratchet of the timing device, the last tooth 47 of. the ratchet being so positioned that when engaged and moved by the pawl of the actuator the abutment 29 will be in substantially the horizontal plane of the axis 22 of-the timing device and in engagement with the arm 30 of .the cutter-withdrawing lever. Reverse movement of the rotatable timing device is prevented by a dog '48 which is pivotally mounted upon a stud 49 upon the arm 35 and desirably is so positioned as to be coincident in its engagement with the ratchet teeth with the pawl 45 when the latter is substantially at the extremity of its actuating movement.

The dog 48 is held in engagement with the ratchet by a helical spring 50 which surrounds the stud 49 and is secured at one end tothe dog 48 and at its opposite end to a sleeve 51 which is pinned to the stud 49. Thus when the last tooth 47 of the actuator has been engaged and actuated by the pawl 45 of the actuator 37 the dog 48 retains the timing device in the position illustrated in Fig. 1 and upon further reciprocation of the actuator by the lay the pawl 45 rides upon the smooth cylindrical surface 52 of the timing device without rotating the same further. The lug or abutment 29 by its engagement with the lever 30 retains the cutting device in. inoperative position so long as the dog 48 engages the last'tooth 47 of the ratchet segment and consequently prevents the actuation of the cutter during the normal operation of the 100m.

In order to permit restoration of the cutter tooperative position upon call for transfer the dog 48 is provided with a laterally extending stud 53 preferably surrounded. by an anti-friction sleeve which is positioned in the path of the arm 5 which is adjustably secured to thecontrollerrod, so that upon call for transfer the rotation of the controller rod 4 in the direction of the arrow shown in Figs. 1 and 2 will raise the dog from its engagement with the end tooth 47 of the ratchet as shown in Fig. l to free the ratchet as illustrated in Fig. 2.

In order simultaneously to release the actuating pawl 45 from engagement with the ratchet the pawl 45 is provided with a lug or arm 54 which extends over the top of the dog 48 so that as the dog 48 is raised the pawl 45 willalso be raised, thus freeing the rotatable timing device and permitting it to, rotate under the action of its spring until arrested by the engagement of the pinr25 with the lug 26 which projects from the plate 18. v I I p In the. operation of the device, during the normal operation of the loom as illustrated in Fig. '1, the dog 48 is in engagement with the last tooth 47 of the ratchet and the re ciprocation of the lay, by the engagement of the hand rail 2 with the head 39 of the actuator, merely causes a reciprocation of the actuator during which the pawl 45 rides uponthe smooth surface 52 of the rotatable timing device, but produces no rotative movement thereof. This action will contin'ue until the automatic mechanism of the loom calls for filling replenishment. Upon call for filling replenishment the controller rod 4 will be rotated in the direction of the arrows illustrated in Figs. 1 and 2 thereby raising the arm 5 from theposition shown in Fig. 1 to the position shown in Fig. 2. During such movement the arm 5 engages the stud 53 upon the dog 46 and raises it together with the pawl 45 out of engagement with the ratchet. hen thus released the rotatable timing member 21 is rotated by its spring 27 in a clock-wise direction as indicated by the arrow in Fig. 1 until the pin 25. upon the timing device engages the lug 26 which projects from the plate 18. Such rotation of the timing device moves the abutment 29 of the timing device out of engagement with the arm 30 of the cutter retracting lever, thus permitting the cutter- 'act'uating spring 14 to move the cutting blade 11 to cutting-position in which the heel 13' of the cutter lies at the rear of the heel 9 ofthe temple so that as the lay beats up the heel 13 of the cutter is engaged and the cutter rocked and. moved backwardly before the lay engages the heel 9 of the temple head. This movement of the cutter causes the hooked end 12 thereof to cooperate with the stationary cutting blade 10 and to sever any filling end which may be caught by the hooked end of the cutter. As soon as the arm 5 of the controller rod is restored to its normal position illustrated in Fig. -1 after call for transfer the pawl 45 and dog 48 drop into engagement with the segmental ratchet 23. Upon each beat-up of the lay thereafter the actuator 38 will be moved to cause the pawl 45 to rotate the timing device and backward rotation of the timing device will be prevented by the dog 48. Such rotation of the timing device will continue until the last tooth 47 has been engaged and actuated and the timing device locked by the engagement of the dog 48 with the said last tooth 47. As the timing device is thus rotated the abutment 29 will be gradually, moved into engagement with the arm 30 of the cutter-retracting lever and will withdraw the cutter from its operative position illustrated in Fig. 2 to its inoperative position illustrated in Fig. 1 and after the abutment 29 has assumed the position illustrated in Fig. l and the end tooth 47 has been engaged by thedog 48 the cutter will be retained in the inoperative position shown in Fig. 1 until transfer is again called for.

Thus means are providedfor permitting the usual cutting action of the temple thread cutter during a predetermined number of beat-ups of the lay and thereafter preventing the actuation of the thread cut ter during the normal running'of the loom until the next call for transfer. By adjusting the position of the pin to a selected pin hole 24; of the timing device the clockwise rotation of the timing device under the influence of its spring 27 may be adjustet so that the number of actuations of the cut ter before it is rendered inoperative may be adjusted to conform to the character of the filling or the running condition of the loom when weaving different kinds of cloth. (Ionsequently the action of the cutter may be limited to til Li which is desirable in the production of any kind of fabric.

It will be obvious that the invention may be applied to any form of device which may be employed to cut or otherwise part the filling and the term parting as used in the following claims is therefore intended to cover all types of mechanisms which serve to sever the thread or filling ends which extend from the selvage edge of the web of cloth during the operation.

It will be understood that the embodiment of the invention disclosed herein is of an illustrative character and is not restrictive and that various changes in form, construction and arrangement of parts may be made within the spirit and scope of the fol lowing claims.
